Be it known that I, EDNA Lu MEYERS, a citizen of the United States ofAmerica, residing at Cameron, in the county of Milam and State of Texas,have invented new and useful Improvements in Wheel-Tire Machines, ofwhich the following is a specification.

This invention relates to machines for applying and removingwheel-tires, and has for its objects to produce a comparatively simpleinexpensive device of this character including devices for performingthe successive steps of removing the nuts from the tire-bolts andwithdrawing the bolts from the felly and tire, one in which the boltsmay be readily inserted for securing the tire in place and the nutsapplied to the bolt and one in which the wheel will be effectuallysupported during the performance of the above-named operations.

With these and other objects in view the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings, Figure 1 is a side elevation of a machineembodying the invention. Fig. 2 is a front elevation of the same. Fig. 3is a detail side elevation of the bolt cutting or nipping device. Fig. 4is a detail view of the operating-lever embodied in the nut -removingmechanism. Fig. 5 is a perspective view of the nut-engaging head orwrench. Fig. 6 is a detail section taken on the line 6 6 of Fig. 1.

Referring to the drawings, 1 designates a or standard to which a frame 2is connected by horizontal braces 3 and diagonal braces 4, connected bya main brace 5, said frame 2,which is preferably composed of platemetal, being provided adjacent its upper end with a vertically-disposedslot 6 and having beneath said slot a horizontal forwardly-openingrecess 7, beneath which in turn the frame has a forwardly-projectingportion or extension 8.

Pivoted to the upper portion of the frame 2, as at 9, is a hand-lever10, provided at its inner end with an arcuate slot 11, designed toreceive a horizontal laterally-projecting bolt or pintle 12, carried bya vertical guide rod or element 13,slidably sustained by bearings 14 andhaving pivoted to its lower end, as at 15, a gripping jaw or member 17to which in turn is pivoted, as at 18, a shank or element 19, providedat its lower end with a gripping-j aw 20 and having at its other end adisk-like head provided with an inclined slot 21, through which thepintle 12 also eX- tends, there being loose upon the pintle within theslots 6 and 11 a wearing-sleeve 21, while tapped onto the outer end ofthe pintle is a nut 22. It is to be understood in this connection thatthe pivotally-connected elements 13 and 19, together with theirgrippingjaws 17 and 20, constitute a bolt-extracting device designed tobe operated by the lever 10, it being apparent that when the outer endof the lever is swung upward the element 13 will be moved verticallydownward in its guides and through the medium of the bolt-and-slotconnection with the element 19 will have sufficient movement relative tothe latter to open the jaws 17 and 20 for engagement with-a bolt, asmore fully hereinafter explained.

Slidably attached to the frame 2 beneath the recess 7, by means offastening members or bolts 23 working in vertical slots 24 in the frame,is a vertically-movable pressure member or head 25, adapted for upwardmovement by means of a lever 26, pivoted to the frame and connected by alink or other rigid element 27 with a foot-lever 28, it being apparentthat when the lever 28 is moved downward the lever 26 will, through themedium of link 27, be actuated for moving the head upward for a purposewhich will presently appear.

Secured to the front side face of the frame 2 is a bearing member orframe 29, presenting a vertical portion and a pair of verticallyspacedhorizontal portions, in which latter there is journaled the shank 30 ofa rotary wrench provided at its upper end with a socketed nut-engaginghead 31, there being fixed upon the shank 30 a bevel-gear 32, engaged bya corresponding gear 33, in turn fixed upon a stub-shaft 34, journaledin the vertical portion of the frame 29 and carrying a ratchet 35,engaged by a double-acting pawl 36, pivoted to a lever 37, looselypivoted upon the shaft 34. When the pawl-lever 36 is properly engagedwith the shaft 34, movement of the lever 37 serves to impart rotarymotion to stub-shaft 34 and, through the medium of the intermeshinggears 32 33, rotates the wrench, it being understood that the directionofrotation of the wrench for applying or removing the nut depends uponthe engagement of the pawl 36 with the ratchet Pivoted to the frame 2 isan arm or lever 38, carrying at its outer end a pressure-head 39,disposed vertically above and in axial alinement with the wrench-head31, there being pivoted to the rear end of lever 38 a hand-lever 40, inturn connected at its lower end by means of a link 41 with the frame,the lower end of link 41 being secured in place by the fastening memberor bolt 42, which serves to attach to the frame the adjacent ends ofbraces 3, 4, and 5.

Secured to the rear side face of frame 2 is a vertically-disposed memberor bar 43, having at its upper end a head 44, provided with a verticalrecess designed to receive a cutting member or head 45 of circular form,pivoted to the member 43 by means of a bolt 46 and provided with anopening or recess 47 and with an operating-handle 48, there beingpresented by the recess 47 a sharpened cutting edge 49, adapted forcooperation with a cutting edge 50 on the head 44 for cutting or nippingbolts in shortening the latter.

In practice when it is desired to remove a wheel-tire the nuts of thetire-holding bolts are successively engaged with and removed by thewrench 31, which latter is-operated in the manner heretofore explained.After removal of the nuts the inner ends of the bolts are placedsuccessively in position upon the pressure member 25, which latter isactuated through the medium of levers 26 and 28 for forcing the boltspartially outward through the felly and tire, each bolt after being thusforced outward being engaged and removed by the bolt-extractor, whichlatter is operated by means of the hand-lever 10, as heretoforeexplained. On the other hand, when it is desired to secure a tire inposition upon a wheel the bolts are seated in their respec tive openingsand forced through the latter by bringing them successively under theaction of the pressure-head 39, carried by lever 38 and actuated bylever 40, each bolt after being forced inward through the tire and fellybeing held in place by means of the pressure member 39 during theoperation of applying the nuts by means of the wrench, as

will be readily understood. In attaching the tire to the felly shouldthe bolts be unnecessarily long they may be cut to the proper length bymeans of the clipping device, comprising heads 44 and 45, having thecooperating cutting edges 49 and 50.

From the foregoing it is apparent that I produce a simple inexpensivedevice admirably adapted for the attainment of the ends in view and onewherein the successive steps necessary to the application or removal ofa tire may be readily effected, it being under-.

stood that in attaining these ends minor frame, a guide-rod movablymounted upon the frame, a jaw pivoted to the guide-rod, a shank pivotedto said jaw and provided with a cooperating jaw, a lever pivoted uponthe frame and provided with a slot, and a bolt carried by the guide-rod,said bolt passing through the slot in the lever and connected to saidshank.
